Have you wondered when you were driving or standing near a window and you happened to take a look up at the sky. See any clouds? If so, ask yourself this: how do clouds stay up in the air?
Clouds are made of water droplets and ice crystals which weigh many tons. So why do clouds do not plummet to the ground?
A cloud’s weight is actually spread out over a very large area. In addition, the cloud’s droplets and crystals are very small; so small, that warm air rising from the earth’s surface is able to keep them floating in the air. It is similar to how dust motes swirl in a shaft of sunlight.
Clouds don’t stay up in the air forever, of course.
